The Creatibles D.I.Y. Air-Dry Clay Kit is everything a budding sculptor could want. The super soft clay makes hand building your creations easy and fun, especially with the help of 3 sculpting tools to add detail and dimensions. With 24 mixable colors to choose from, the possibilities are limited only by your imagination. Once your project is complete, simply leave it out, and it will harden on its own. Then, if you would like to decorate further, you can use paints or markers to finish the piece. The 24 clays come in 6 airtight tubs to keep the clay fresh. Suitable for ages 6 and up.
